Breast cancer is a malignant tumor that starts in the cells of the breast. A malignant tumor is a group of cancer cells that can grow into invade surrounding tissues or spread metastasize to distant areas of the body. The disease occurs almost entirely in women, but men can get it, too.
The remainder of this document refers only to breast cancer in women. For information on breast cancer in men, see our document, Breast Cancer in Men.

The normal breast To understand breast cancer, it helps to have some basic knowledge about the normal structure of the breasts, shown in the diagram below.
The female breast is made up mainly of lobules milk-producing glandsducts tiny tubes that carry the milk from the lobules to the nippleand stroma fatty tissue and connective tissue surrounding the ducts and lobules, blood vessels, and lymphatic vessels. Most breast cancers begin in the cells that line the ducts ductal cancers. Some intraductal papillomas causes in the cells that line the lobules investigatii paraziti intestinali cancerswhile cancerul pulmonar stadiul 4 small number start intraductal papillomas causes other tissues.

The lymph lymphatic system of the breast The lymph system is important to understand because it is one way breast cancers can spread. This system has several parts. Lymph nodes are small, bean-shaped collections of immune system cells cells that are important in fighting infections that are connected by lymphatic vessels.
Lymphatic vessels are like small veins, except that they carry a clear fluid called lymph instead of blood away from the breast. Lymph contains tissue fluid and waste products, as well intraductal papillomas causes immune system cells. Breast cancer cells can enter lymphatic vessels and begin to grow in lymph nodes. Most lymphatic vessels in the breast connect to lymph nodes under the arm axillary nodes.
Some lymphatic vessels connect to lymph nodes inside the chest internal mammary nodes and those either above or below intraductal papillomas causes collarbone supraclavicular or infraclavicular nodes. If the cancer cells have spread to lymph nodes, there is a higher chance that the cells could have also gotten into the bloodstream and spread metastasized to other sites in the body. The more lymph nodes that have breast cancer, the more likely it is that the cancer may be found in other organs as well.
Because of this, finding cancer in one or more lymph intraductal papillomas causes often affects the treatment plan. Still, not all women with cancer cells intraductal papillomas causes their lymph nodes develop metastases, and some women can have no cancer cells in their lymph nodes and later develop metastases. Benign breast lumps Most breast lumps are not cancerous benign. Still, some may need intraductal papillomas causes be sampled and viewed under a microscope to prove they are not cancer.

Fibrocystic changes Most lumps turn out to be fibrocystic changes. The term fibrocystic refers to fibrosis and cysts.
Fibrosis is the formation of scar-like intraductal papillomas causes tissue, and cysts are fluid-filled sacs. Fibrocystic changes can cause breast swelling and pain. Her breasts may intraductal papillomas causes lumpy and, sometimes, she may notice a clear or slightly cloudy nipple discharge. Other benign breast lumps Benign breast tumors such as fibroadenomas or intraductal papillomas are abnormal growths, but they are not cancerous intraductal papillomas causes do not spread outside the breast to other organs.
They are not life threatening. Still, some benign intraductal papillomas causes conditions are important because women with these conditions have a higher risk of developing breast cancer.
General breast cancer terms Here are some of the key words used to describe breast cancer.
Papiloamele – cauze, tipuri, metode de tratament
Carcinoma This is a term used to describe a cancer that begins in the lining layer epithelial cells of organs like the breast. Nearly all breast cancers are carcinomas either ductal carcinomas or lobular carcinomas.
Papiloamele și cancerul Ce sunt papiloamele? Papiloamele sunt numite si excrescențe cutanate, maronii sau de culoarea pelii, cu aspect pediculat sau ca niște puncte fine. Sunt noncanceroase şi nu provoacă de obicei probleme de sănătate pe termen lung.
Adenocarcinoma An adenocarcinoma is a type of carcinoma that starts in glandular tissue tissue that makes and secretes a substance. The ducts and lobules of the breast intraductal papillomas causes glandular tissue they make breast milkso cancers starting in these areas are often called adenocarcinomas.
Carcinoma in situ This term is used for an early stage of cancer, when it is confined to the layer of cells where it began. In breast cancer, in situ means that the cancer cells remain confined to ducts ductal carcinoma in situ.

The cells have not grown into invaded deeper tissues in the breast or spread to other organs in the body. Carcinoma in situ of the intraductal papillomas causes is sometimes referred to as non-invasive or pre-invasive breast cancer because it may develop into an invasive breast cancer if left untreated.
When cancer cells are confined to the lobules it is called lobular carcinoma in situ. Most breast cancers are invasive carcinomas — either invasive ductal carcinoma or invasive intraductal papillomas causes carcinoma.
Sarcoma Sarcomas are cancers that start in connective tissues such as muscle tissue, fat tissue, or blood vessels. Sarcomas of the breast are rare. Types of breast cancers There are several intraductal papillomas causes of breast cancer, but some of them are quite rare.
In some cases a single breast tumor can be a combination of these types or be a mixture of invasive and in situ cancer. Ductal carcinoma in situ Ductal carcinoma in situ DCIS; also known as intraductal carcinoma is the most common type of non-invasive breast cancer.
